Fixed-Order ${
m H}_{infty}$ Decentralized Control with Model Based Feedforward for Elastic Web Winding Systems Conference Paper uri icon


  • This paper presents centralized and decentralized fixed order ℋ∞ controller designs with model based feedforward for web winding systems which provide improved web tension and velocity regulation. First, mathematical models of the fundamental elements in a web process line are presented. An improved state space model is then derived for the entire system; the model enables calculation of the phenomenological model feedforward signals and helps in the synthesis of ℋ∞ controllers around the set points given by the reference signals. Different ℋ∞ control strategies with additive feedforward have been synthesized, especially ℋ∞ based PI controllers which are relevant for industrial applications. The strategies have been validated on a nonlinear simulator identified on a 3-motor winding test bench. © 2006 IEEE.
